2 Claims. (01. 103-28) This invention relates. to pump operating mechanism. Q 1

An object of the invention is to provide mechanism of the character described whereby a pump may be driven from a suitable motor and automatically clutched therewith and declutched therefrom in accordance with the level of the liquid in the tank supplied from the pump.

Another object of the invention is to provide, in a device of the character described, means for automatically priming the pump.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 shows a side elevation of the apparatus showing the tank in section.

Figure 2 shows an enlarged, fragmentary, vertical sectional view of the tank, showing the float and the float operated valve mechanism associated with the tank.

Figure 3 shows a plan view of a clutch employed.

Figure 4 shows a side elevation thereof, and

Figure 5 shows a pulley assembly employed.

In the drawings the numeral 1 designates a supporting framework on which the tank 2 is mounted.

Within the tank there are the vertical guides 3, 3 whose lower ends are secured to the bottom of the tank and whose upper ends are secured to the cross-beam 4 at the top of the tank. The numeral 5 designates a hollow float having the weight 6 therein. This float has the ears 7, '7 at its ends having bearings to receive the guides 3 whereby the float is confined to a vertical movement.

Attached to the cross beam 4 between the guides 3 there is a pulley frame 8 having the pulleys 9, 9 and 10, 10 rotatably mounted therein. A cable 11 is attached to the top of the float and passes over the pulleys 9, 9 and thence downwardly through the tube 11 which is secured to the bottom of the tank and stands up above the level of the liquid in the tank. A cable 12 is attached to the bottom of the float and passes around a pulley 13 attached to the bottom of the tank and thence over the pulleys 10, 10 and down through the tube 14 which is secured to the bottom of the tank and stands up above the normal liquid level thereof.

There is a supply pipe 15 leading upwardly from the centrifugal pump 16 and into the botis located beneath the float 5.

tom of the tank and this supply pipe 15 has the upward flared valve seat 1'? at its upper end which is .controlled by the tapering valve 18 inclosed within the valve cage .19 which is located within tank 2. Upstanding from said 5 valve there is a stem 19 whose upper end has a pivotal sliding connection with a lever 20 which is pivoted on the standard 21 located within the tank. The other end of the lever 20 There is a magneto type generator motor 22 located on a suitable foundation beneath the tank 2 and associated with and driven by this motor there is an electric generator 23 having the driven shaft 24. The centrifugal pump 16 is driven by the pump shaft 25 and the shafts 24 and 25 may be clutched and declutched by means of a suitable clutch mechanism of conventional construction within the housing 26. This clutch mechanism is operated in the usual and well known manner through the clutch operating shaft 2'? which extends transversely through, and is mounted in hearings in the clutch housing 26.

Fixed on one end of the shaft 27 there is a yoke 28 and adjustably mounted on the ends of said yoke are the rods 29, 30. The lower end of the cable 11 is attached to the rod 29 and the lower end of the cable 12 is attached to the rod 30.

An inlet line as 3'7 leads from the well, or other source of supply to the pump. When the supply of liquid in the tank 2 becomes low the float 5 will have descended and will strike the end of the lever 20 beneath it and will lift the valve 18, permitting suflicient water to pass downwardly through the pipe 15 to prime the pump, and at the same time the cable 11 will operate through the adjusting rod 29 to actuate the clutch shaft 27 to engage the clutch. The pump will thus be operated to pump liquid into the tank and the float 5 will be correspondingly elevated and when a predetermined level has been reached the float will operate through the cable 12 to reverse the position of the yoke 28 and to actuate the clutch shaft 27, to release the clutch whereupon the pump will be stopped.

The drawings and description disclose what is now considered to be a preferred form of the invention by way of illustration only, while the 50 broad principle of the invention will be defined by the appended claims.

What I claim is:

1. The combination with a tank, of a supply line entering the bottom of the tank, and having 55 a flared valve seat, a pump connected into the line, a valve arranged to cooperate with the seat and controlling said line and arranged to be maintained open by the pressure of liquid delivered through said line by said pump, a motor, means including a clutch for connecting the motor with and for disconnecting the same from the pump, a float in the tank, cables operatively connected to the float and clutch whereby the clutch may be disconnected upon the elevation of the float, andwhereby the clutch may be engaged upon descent of the float, upstanding guide tubes anchored to the bottom of the tank and extending above the leveliof the liquid in the tank through which the cables operate, and means arranged to be operated by the float to open the valve upon such descent of the float.

2. The combination with an elevated tank, of-

vertical guides therein whose lower ends are secured to the bottom of the tank and whose upper ends are oonnectedby. a cross beam, a hollow float having a weight therein and having lateral bearings to receive said guides, a pulley frame on the cross beam having pulleys therein,

a pulley at the bottom of the tank between said guides, spaced tubes attached to the bottom of the tank and upstanding therein, a cable attached to the top of the float and operating over pulleys in said frame and passing downwardly through one of said tubes, a second cable attached to the bottom of the float and operating over the pulley at the bottom of the tank and thence over a pulley in said frame and passing thence downwardly through the other of said tubes, a supply line entering the bottom of the tank and having a valve seat, a pump connected into the line, a valve arranged to cooperate with said seat and controlling said line, a motor; means including a clutch for connecting the motor with and disconnecting the same from the pump, said cables being operatively connected with the clutch whereby the clutch may be disconnected upon elevation 01 the float and engaged upon descent of the float, a pivotally mounted lever arranged to be operated by the float to open the valve upon. the descent of the float.
